NEW HAVEN, Conn. – Celebrity lawyer Mickey Sherman yesterday agreed to an ethical reprimand for improperly billing an NYU student client who is headed to prison for swindling millions of dollars.

“Just because I did some conning doesn’t mean he has the right to do it,” said admitted scam artist Hakan Yalincak, who made the ethics complaint against his former lawyer.

The lawyer originally represented Yalincak, now 22, when the student was under investigation for credit-card fraud – but later withdrew after the young man was indicted for hedge-fund fraud in 2005.

Yalincak is expected to surrender next week to begin serving a 31/2-year federal prison sentence.

Sherman admitted he failed to give Yalincak a required written document showing they had verbally agreed to $175,000 in legal fees. Sherman also admits failing to adequately answer a local oversight panel’s inquiry.

Outside court yesterday, Sherman’s lawyer, Anthony Nuzzo, called Yalincak “scary” and accused him of spinning a web of lies.

“You are the ultimate evil person,” Nuzzo told Yalincak. “Have a good time in jail. Watch out for the bathrooms.”

Three other alleged violations – gross overcharging, mismanagement of fee money, and giving Yalincak a partial refund in exchange for the complaint being dropped – will be dismissed. There is no fine.
